On September 28th at roughly ~9:45 pm UTC, Microsoft reported an issue affecting multiple Microsoft 365 services.
Microsoft reported that they were working to identify the full impact and that they would provide more information shortly.
Users were encouraged to look for more information on the outage in the admin under M0222965 as well as status.office.com. Unfortunately, many users were receiving reports that all services were up and running while others were unable to access the site all together.
At ~10:15pm UTC, Microsoft reported that they had identified a recent change that appeared to be the source of the issue and were rolling back the change to mitigate impact.
Shortly after Microsoft reported that they had rolled back the change that was likely the source of impact and are monitoring the environment to validate that service is recovering.
Unfortunately, shortly after Microsoft reported that they had implemented a fix, they shared that they were not observing an increase in successful connections after rolling back a recent change and that they were working to evaluate additional mitigation solutions.
Over 2 hours after Microsofts initial post about the Microsoft 365 services outage, Microsoft reported that they were rerouting traffic to alternate infrastructure to improve the user experience while they continue to investigate the issue.
Finally just after ~12:30 pm UTC, Microsoft reported that they had started seeing improvement for multiple services after applying mitigations steps and that they would continue to monitor the situation.
